# Fix a return-without-value from a non-void function. This warning

# problem. Now it makes the 'cg' binary segfault. So:

# Not quite ready to install: the PREFIX override doesn't entirely work
# because the st binary was built from st.O (obcpl's parsed syntax tree
# format) which has the /usr/local/lib path baked into it (not affected
# by the sed command, above). st.O is distributed this way because obcpl
# needs to be buildable on a system without an existing BCPL compiler. So
# we need to regenerate st.O from st.b (its BCPL source), then rebuild
# st from st.O. This works because st will look for its includes in the
# current dir first. This is the sort of thing gcc has 'make bootstrap'
# for...
rm -f st.O
./st < st.b > st.O
rm -f st st.s st.o
make st
# Now we're good to go.

# 20210906 bkw: build utils too. have to use a custom obcpl wrapper
# that runs the uninstalled binaries and make sure LIBHDR can be found
# in the current dir (see above). Install them with obcpl- prefix
# because 'gpm' is a conflict with Slackware's gpm, and 'xref' is
# a pretty generic name (can't guarantee there's no other xref command
# on SBo).
